Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Area of Science:

  • Biochemistry
  • Neuroscience
  • Molecular Biology

Background:

  • Sirtuins are NAD+-dependent enzymes involved in aging, metabolism, and cellular stress responses.
  • Their roles in the nervous system, neurodegeneration, and metabolic syndrome are increasingly recognized.
  • Dysregulation of sirtuin activity is implicated in various neurological disorders.

Purpose of the Study:

  • To review the diverse functions of sirtuins, focusing on their involvement in the nervous system and neurodegenerative diseases.
  • To discuss the differential expression and subcellular localization of sirtuins and their impact on function.
  • To highlight the potential of small molecules for modulating sirtuin activity as a therapeutic strategy.

Main Methods:

  • Literature review of studies on sirtuins, neurodegeneration, and brain expression.
  • Analysis of research on sirtuin modulation by small molecules.
  • Synthesis of information regarding sirtuin functions and localization.

Main Results:

  • Sirtuins play significant roles in regulating neuronal function, inflammation, and protein aggregation.
  • Evidence suggests that manipulating sirtuin activity, particularly SIRT1, can influence neurodegenerative disease models.
  • Subcellular localization is critical for determining specific sirtuin functions.

Conclusions:

  • Sirtuins represent promising therapeutic targets for neurodegenerative disorders.
  • Further research into sirtuin biology and small molecule modulators is warranted.
  • Understanding sirtuin expression and function in the brain is key to developing novel treatments.
